Cheap Tricks for Interaction

This example demonstrates a zoomable world map with country outlines and hover highlighting, rendered as SVG. The map uses D3's `geoNaturalEarth1` projection and `geoPath` to draw country shapes from the world-atlas TopoJSON dataset, with a sphere background. Interactive zoom is implemented via D3's `zoom` module, which applies a transform to the map group on zoom events. Country names are joined from TSV data, and hovering over a country fills it red via CSS `.country:hover`. The visualization is built with React and D3 v5.

This example shows a zoomable world map rendered with D3 v5 and TopoJSON, where hovering over any country highlights it in red. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw country boundaries from the world-atlas 50m dataset, with country names added as tooltips using `<title>` elements. Interaction combines `d3.zoom` on the SVG for pan and zoom transformations, plus CSS `:hover` styling for the highlight effect. The base map and sphere are drawn as SVG paths, with data joined from TSV metadata and JSON topology.

This example demonstrates a zoomable world map rendered with SVG paths using D3.js. It shows country boundaries from the world-atlas TopoJSON dataset, with each country labeled by name via a title tooltip on hover. The visualization uses a natural Earth projection and implements pan-and-zoom interaction through d3.zoom, which applies a transform to the map group. Countries are colored light green and highlight red on hover, while the sphere background is dark blue. The code fetches both TopoJSON geometry and TSV country names concurrently with Promise.all.

This example shows a zoomable, hover-highlighted world map rendered with SVG. It uses d3.geoNaturalEarth1 projection and d3.geoPath to draw country boundaries and the ocean sphere, with country names from a world-atlas TSV file. Zoom interaction is implemented via d3.zoom and event transforms, while hover effects are styled with CSS. The code loads TopoJSON and converts it to GeoJSON using topojson.feature.

This example demonstrates a world map with zoom and hover interactions. Using D3’s `geoNaturalEarth1` projection and `geoPath`, it renders country boundaries from TopoJSON world-atlas data, with country names loaded via TSV. A D3 zoom behavior on the SVG applies a transform to the map group, enabling pan and scale. Hovering over a country changes its fill to red via CSS, highlighting the selected region.

This example shows a zoomable world map with country name tooltips, rendered as an SVG using D3 v5 and TopoJSON data from the world-atlas package. It displays natural Earth projection with interactive pan and zoom via d3.zoom, while country boundaries are drawn with d3.geoPath. Hovering highlights countries in orange through CSS, and each path appends a <title> element populated from the TSV dataset for native browser tooltips. The map uses a simple geoNaturalEarth1 projection with a steelblue sphere background.

This example demonstrates interactive pan and zoom on a world map, with countries highlighted in red on hover and tooltips displaying country names via SVG `<title>` elements. It uses a natural Earth projection (`geoNaturalEarth1`) and renders geographic features with `d3.geoPath`. The map loads world-atlas TopoJSON data and merges it with TSV country names, while the zoom behavior is implemented through `d3.zoom` applied to an SVG group.
